When the operator loads the mons and checks for a valid maxMonId
the check of the id against the currently running mons was outdated
from legacy mon ids. The check now has to parse the new id which is
just the letter instead of having a number from legacy mon ids.
Without this fix, the maxMonId would stay incorrect if it was somehow
corrupted.
